Whatever your business, consider organizing what you sell into groups of three products, and giving each group a number. For example, if you run a coffee shop, one group could be “a machiatto, a ginger cookie, and a kale salad.” Another group could be “a soft boiled egg and two single-espressos.” You get the idea.
That way, when a customer walks in, they can say “I’ll have the number one!” People love to say that phrase. Just look at how well McDonald’s has done!
Now sit back and watch the money roll in.
This reminds me of the early days of computers, when we used to buy ones and zeroes individually.
